    go-gcc: set DECL_NAMELESS for temporary variables
    
            * go-gcc.cc (Gcc_backend::static_chain_variable): Set
            DECL_NAMELESS on the new decl.
            (Gcc_backend::temporary_variable): Likewise.
            (Gcc_backend::function): Set DECL_NAMELESS on the result decl.
